How to choose a CAEN code for a company in Romania: mistakes Ukrainian entrepreneurs make
The CAEN code for a company in Romania is not a technical detail.
It is the foundation of what the company will officially do.
When opening an SRL, many Ukrainians think:
"Let's add as many codes as possible so we can do everything later."
At first glance, this seems convenient.
But in reality, the wrong choice of CAEN can create problems: with the bank, accounting, contracts, tax logic, the residence permit, real estate and explaining what the company does.
That is why CAEN should be chosen not "just in case," but to fit the actual business model.
What CAEN is
CAEN is the classification of economic activities in Romania.
Put simply, these are codes that show what a company is allowed to do.
If an SRL provides consulting services, it needs one set of codes. If it deals in real estate, another. If it works in advertising, a third. If it manages properties, does renovations, rents out real estate, sells goods or provides IT services, the logic will be different.
CAEN must reflect the actual activity, not a fantasy about the future.
Why CAEN should be chosen before registration
CAEN is chosen at the stage of preparing the company.
If it is chosen incorrectly, the company may be registered but awkward to operate.
For example:
the client wants to work in real estate, but the codes do not fit; consulting is planned, but the activity is described too broadly; rentals are needed, but the codes have not been thought through; work with a bank is planned, but the business model is unclear; a residence permit through business is needed, but the company does not show real activity; the accountant does not understand how to record transactions correctly.
A company can be opened quickly.
But fixing the structure later is harder than choosing correctly from the start.
Main and additional CAEN codes
A company usually has a main activity and additional ones.
The main CAEN code should answer the question:
what is the company's main activity?
Additional CAEN codes show what else the company can do.
But it is important not to overdo it.
If you add too many unrelated lines of business, the company can look chaotic.
For example, a company simultaneously declares consulting, trade, renovation, real estate, advertising, transport and ten other lines of business.
To a bank and an accountant, this may look not like a strong structure, but like the absence of a clear model.
Fewer, but more precise, is better.
CAEN and the bank
A bank looks not only at the company's documents.
A bank looks at the substance of the business.
If the CAEN codes list different activities, the bank may ask:
what you actually do; who your clients are; where the money will come from; what contracts there will be; why the company was opened in Romania; which countries are involved in the payments; what turnover is expected.
If the CAEN code was chosen at random, it is harder to explain the business.
If the CAEN code matches the actual model, it is easier for the bank to understand the company's logic.
That is why choosing CAEN is directly linked to preparing the bank account.
CAEN and accounting
Accounting also depends on the activity.
Different types of business may involve different documents, expenses, contracts, invoices, tax issues and reporting.
For example:
consulting has one contract logic; renting out real estate, another; renovation and design, a third; advertising, a fourth; trade, a fifth.
If the CAEN code does not match the actual transactions, it is harder for the accountant to run the company properly.
And if the company is linked to a residence permit, weak accounting can weaken the whole route.
CAEN and the residence permit
Many Ukrainians open an SRL in Romania with a residence permit in mind.
But the company by itself should not be seen as an automatic status.
If a business route is genuinely being considered, CAEN becomes an important part of the logic.
You need to show:
what the company's activity is; why it is real; where the income comes from; who the clients are; what the contracts are; what the accounting is; how the activity is connected to staying in Romania.
If CAEN is chosen incorrectly, the business route looks weaker.
If it is chosen correctly, it helps show the company's economic logic.
CAEN for real estate
Real estate is a separate topic.
Many Ukrainians open a company in Romania because they want to buy, rent out or manage properties, or work with investments.
But real estate is a broad subject.
You need to understand what exactly the company does:
buys a property; rents it out; manages properties; provides agency services; does renovations; does design; services tenants; structures an investment project.
Each scenario needs its own logic.
You cannot say: "Let's just put something about real estate."
You need to understand the model and choose codes to fit it.
CAEN for consulting and services
If the company provides consulting services, you need to describe precisely what those services are.
Consulting can be:
management; business consulting; marketing; investment; organizational; client support; services for businesses.
You cannot just write "consulting" without understanding how contracts, invoices and the result of the service will be documented.
For a consulting company, it is especially important that CAEN matches the contracts and the actual work.
Mistakes when choosing CAEN
Mistake #1. Choosing codes at random.
Mistake #2. Adding too many unrelated activities.
Mistake #3. Copying CAEN codes from someone else's company.
Mistake #4. Not taking the bank into account.
Mistake #5. Not taking accounting into account.
Mistake #6. Not taking the residence permit into account.
Mistake #7. Not taking real estate into account.
Mistake #8. Not understanding what contracts the company will have.
Mistake #9. Not linking CAEN to real clients.
Mistake #10. Choosing CAEN before analyzing the business model.
How to choose CAEN correctly
The right order is:
first describe the business; understand the clients; understand the services or goods; identify the sources of income; check the contracts; understand the bank; assess the accounting; take the residence permit into account, if needed; take real estate into account, if there is any; only then choose the main and additional CAEN codes.
CAEN must serve the business model, not replace it.
If there is no business model, it is too early to choose codes.
How Alliance / Armonie helps
Alliance / Armonie helps Ukrainians choose CAEN codes for an SRL in Romania not as a formality, but strategically.
In the assessment, we review:
what business you want to run; who your clients are; what services or goods there will be; what contracts are needed; which bank is needed; what accounting will be required; whether there will be a residence permit; whether there will be real estate; whether employees are needed; what expenses are planned; what the plan is for 1–3 years.
After the assessment, it becomes clear which CAEN code should be the main one, which codes are needed as additional ones, and which are better left out unless necessary.
What to send for an initial assessment
For an initial analysis, send:
what you want to do; what services or goods you sell; who your clients are; which countries the payments will come from; whether a bank is needed; whether accounting is needed; whether a residence permit is of interest; whether there is real estate; whether there will be rentals; whether there will be consulting; what income is expected; what your main question about the company is.
That is enough to start the review.
Conclusion
CAEN for a company in Romania should be chosen not as a formality, but as the foundation of future activity.
The right CAEN code helps the bank understand the business, the accountant run the company, clients sign contracts, and the owner build a clear European structure.
The wrong CAEN code creates chaos.
First the business model. Then the clients. Then the contracts. Then the bank and accounting. Then the main and additional CAEN codes.
That way, an SRL in Romania becomes a working tool, not a random registration.
FAQ
Can I choose many CAEN codes just in case?
You can add additional activities, but an overly broad and chaotic set can look like a weak business model.
What matters more: the main CAEN code or the additional ones?
The main CAEN code shows the company's principal activity. The additional ones should support the actual model.
Can CAEN be changed later?
It can be changed, but it is better to choose correctly from the start so you do not have to rework the structure.
Does CAEN matter for a residence permit?
If the residence permit is linked to a business, CAEN must match the SRL's actual activity.
Where do I start choosing CAEN?
With a strategic assessment of the business model.
